THE SINGLE BEST STRATEGY TO USE FOR HGGA2S4 CRYSTAL

Optical parametric oscillator pumped at ~one µm with intracavity mid-IR difference-frequency generation in OPGaAsWe report on the femtosecond optical parametric oscillator (OPO) for the deep-infrared (deep-IR) determined by the Kerr-lens-manner-locked Ti:sapphire laser given that the pump resource. By deploying a novel cascaded intracavity arrange
